Why choose it

The Alcasa cable balances speed and reach. Its 5 Gbps bandwidth is ten times faster than USB 2.0, so large photo libraries or video projects transfer in a fraction of the time. The 3-metre length gives you freedom to position devices without crowding your workspace, and the double-shielded construction reduces interference for stable connections. Nickel-plated connectors resist corrosion, extending the cable's life even with frequent plugging and unplugging.

Ideal use cases

• Syncing and charging older Android smartphones or tablets that use Micro-USB.
• Connecting external hard drives or SSDs with Micro-B ports for fast backups.
• Linking digital cameras, action cams, or GPS units to a PC for file transfer.
• Extending the reach of USB peripherals in a home office or studio setup.

Good to know

This cable supports charging up to 4.5 W (5 V, 0.9 A), which is adequate for many portable devices but not intended for high-wattage fast charging. It works out of the box with Windows, macOS, Linux, and Chrome OS—no drivers needed. The PVC jacket is durable and flexible, while the tinned copper conductors ensure reliable signal integrity over the full 3-metre span.
